Also here are interesting examples, if you bought a Masi built in Carlsbad as late as 1976, it had 1973 date coded parts, they bought a big lot of parts initially and never went through them all. It was somewhere in 1976 that Schwinn finally used up the 151 bolt circle pista cranks, the 144 being availible for some time, but Schwinn and many distributors were selling off the old stock first.
In 1975 I bought 151 BCD pista cranks as they were easier and cheaper to find chainrings for at that time.
So it goes.
Rossignoli tangent!
In 1968 or perhaps late '67 I bought a Rossignoli from Turin Cycle Co-op in Chicago. I had really wanted a PX-10, but for the same price this was the best they had. It was an unstamped frame from Cicli Rossignoli, long road geometry of the mid or early '60s, had a Magistroni crank and BB, Record (not Nuovo!) gearset, Brooks Pro saddle, 15-25 cluster, TTT stem/bars/seat pillar, an odd set of Campy Record/Nisi wheels with D'Alessandro Mondial tires, and odd steel Sheffield pedals. I loved it. The shop guys suggested that it may have been assembled at the distributor in Chicago, from early '60s or earlier racing parts. Not light, but very smooth. NOS, but still new. Where does this odd machine fit into any of this?
I wish I had or at least understood that frame, given what I know now!
